There are rare case reports of tracheal diverticula or paratracheal air cysts. These cases, however, were reported mostly as incidental sonographic or radiologic findings without histologic confirmation. Furthermore, the handful of studies that describe this entity histopathologically report only cases in patients with prior respiratory symptoms. Here, we report a rare case of an asymptomatic 6...

Neuropathologic assessment of chemically induced developmental alterations in the nervous system for regulatory purposes is a multifactorial, complex process. This calls for careful qualitative and quantitative morphologic study of numerous brains at several developmental stages in rats. Quantitative evaluation may include such basic methods as determination of brain weight and dimensions as we...

We evaluated the role of flow cytometric immunophenotyping (FCI) in the assessment of bone marrow (BM) specimens in 104 patients with mantle cell lymphoma (MCL) following treatment with aggressive combination chemotherapy. Of the patients, 77 had no morphologic or FCI evidence of MCL, 13 had morphologic and FCI evidence of MCL, and 14 patients were morphologically negative but FCI showed CD5+ c...

Cross-sectional imaging can play an important role in the pretreatment evaluation of gynecologic cancer patients. In cancer of the uterus, cross-sectional imaging offers an assessment of morphologic prognostic factors, including tumor size, depth of penetration, stage of disease, and lymph node status. Imaging should be viewed as a complementary tool rather than as competitive with the other me...

Introduction: A strong relationship exists between cigarette smoking and the development of oral squamous cell carcinoma. Smoking can significantly increase cellular proliferation. Nevertheless, there is little reference in literature to the cytological assessment of oral mucosa in this respect. Methods: Changes in nuclear and neucleolar cytomorphometric parameters such as diameter, surface, nu...

Abstract The theranostic concept to use diagnostic and therapeutic nuclides image treat cancer was established many years ago for thyroid disease. With the success of [ 177 Lu]-labeled agents targeting neuroendocrine tumors or prostate cancer, interest this has been significantly rising. possibility localize quantify a target within patient opens up novel possibilities, but also challenges sele...

BACKGROUND There is a variable degree of accuracy in discriminating benign from malignant soft tissue masses based on signal intensity and morphologic characteristics by magnetic resonance imaging (MRI). The aim of this study was to determine the utility of detailed component pattern assessment, in addition to morphologic study, for differentiating benign from malignant soft tissue masses by MR...
